James... 1406? Don't see that # have tried 1409 on the dyno and saw no difference from the crane H-11 regular counterpart... however we weren't experencing any valve float to 7600 on the perticular Stocker engine we tried them on..but...they may help on perticular low lobe lift, low valve lift combo's like 283's that need to go to 7500 plus and are having problems with float caused by harmonics,,,,,,,also consider the new push rod rule / tapered / also reduces harmonics, they say you can drill the pushrod guide hole to fit larger pushrods.. so if it' tapered and wont fit in a guide plate, use post 86 rail rockers to keep the rocker on the valve stem. Don't use aftermarket ones... the best are old original LT1 or GM Perf in the yellow cataloge set of 16 / best value. If your using 7/16 studs, grind them & make them work
James... I'm a succer for 66 chevy II's... had an original L79 in 68 and turned it into a C/MP miss that car...
